ABSTRACT:
A staged, superposition gaseous fuel burner provides substantial reduction of nitrogen oxide content in the combustion gases by providing a transverse turning plate in the burner tip and by staging the delivery rich combustion gases, by introducing premix gaseous fuel in stages spaced with respect to incoming secondary air, thereby exposing the incoming secondary air to spaced stages of the rich mixture.
